What is the role of the Kuiper Belt objects in the study of the early solar system?

Kuiper Belt objects (KBOs) are small, icy bodies that orbit beyond Neptune in a region known as the Kuiper Belt. They are believed to be remnants from the formation of the solar system and thus provide valuable information about its early history. KBOs are thought to be some of the most primitive objects in the solar system, having remained largely unchanged since their formation over 4.5 billion years ago. They are composed of volatile ices and organic compounds that may have played a role in the origin of life on Earth.

Studying KBOs can help scientists understand how the early solar system evolved, including the processes that led to the formation of the giant planets, such as Jupiter and Saturn. It can also provide insights into the formation of comets and other small bodies, which can help us understand the role these objects may have played in delivering water and organic material to Earth. Additionally, KBOs can help us better understand the dynamics of the outer solar system, including the gravitational influence of Neptune and the potential existence of a ninth planet beyond Pluto.
